hello people,

 

I have made a block with many bugs I don't understand.

 

problem 1: If I restart minecraft, all the block changes to grass.

problem 2: if I hit the block, the block gives the texture for grass for a half second.

problem 3: If I am close enough, the block spreads as fast as I can run.

But if I am further away, the block doesn't spread at all.

problem 4: if an entity walks over the block, the wither effect doesnt work, it is a sort of corrupt.

 

here is the class:

}




}

I looked in the grass code.

And in my class I changed randomDisplayTick in updateTick and added needs random tick.

Now every problem is just fixed.
